Is The PCR Test For COVID-19 Accurate?
COVID-19Common questionIs the PCR test for COVID-19 accurate?PCR tests remain the gold standard for detecting an active COVID-19 infection. The tests have accurately detected COVID-19 cases since the pandemic began. Highly trained clinical professionals are skilled at correctly interpreting PCR test results and notices like this one from the WHO.
